ASSEMBLING MECHANISM OF TYPOGRAPHICAL COMPOSING- MACHINES.

Application filed June 9, 1925, Serial No. 35,867, and in Great Britain June 13, 1924.

This invention relates to the assembling mechanism of typographical composingmachines such as those known commercially under the trademark linotype and kindred machines of the kind which are provided with a plurality of superposed magazines from aplurality of which matrices can be assembled without involving the shifting of said magazines.

More particularly it releases to machines of the just-named kind in which a guide Way for the-matrices, adjustable into operative relationship with the front ends of different magazines, constitutes part of the assembling mechanism. v

The adjustment of such guideways has heretofore been effected manually through, for example, a system of levers operated by a handle in the vicinity ofthe keyboard,;

the work involved in the movement of the parts being thus imposed upon the operator.

The present invention contemplates an ar rangement which relieves the operator of this work and enables the shift to be effected through the actuation of a key serving to control power-operated mechanism by which the guideway is adjusted.

The invention will now'be described by reference to the accompanying drawings which are illustrative of a preferred con structional form and in which Figurel, is a front elevationof the pertinent parts of the mechanism, and

Figure 2, is an elevation of the same as viewed from the right-hand side of the machine.

In carrying out the invention in the manner here illustrated, there is employed a mechanical relay, which is virtually a reps lica of that described for a different pur pose in Letters Patent 1,105,157. That being so, it is not deemed necessary herein to describe anything beyond the salient features of the said relay. To assist the reader in identifying the different partsof this relay wit-h the corresponding parts described in the said patent, these parts are designated by the samereference numerals in both cases, and to distinguish therefrom the elements of the particular arrangement according to the present invention from the said known parts, these elements are herein identified by reference letters.

mechanical relay comprises a mutiout of that, path during the partial rotation,

of the wheel 107, through a stationary cam123.

In applying the aforesaid relay to the purposes of the present invention, the constantly rotated gear wheel 105 issecured to a shaft B which may be driven by sprockets C, D, and chain E, from the so-called intermediate shaft F, and. a cam 108 rotated with the mutilated gear wheel 107, is arranged to bear on the rear end of a lever G, which serves to adjust the guideway's H; There are two diametrically opposite gaps in the mutilated gear wheel 107, and two co-operating plungers 118, the protrusion of either of which latter, through the actuation of the key A ,as above mentioned, ,willresult in the said mutilated gear wheel 107 and the cam 108 being rotated through 180 and the consequent movement of the guideway-adjusting lever G to one or other of its two terminal posit-ions, thus, through intervening connections, controlling the position of the guideway H. I 1

The form of the last mentioned connec tions may vary according to the construction of guideway with which the devices are to be employed. For the known form of guideway H shown in the drawings, which heretofore, has been manually operated through a link I pivotally connected with lever arms J acting through links K on the ,guideway supports L, the lower end of this same link I is guided as between rollers M, and through a. roller N thereon, bears upon the front end of the adjusting lever G, under the weight of the pertinent parts assisted by a spring 0 which, in the construction illustrated, encircles the link I, these means serving to constantly maintain a roller G on the rear end of the lever G, in contact with the periphery of the cam 108, or in engagement with one or other of the two recesses 131,

till

132 in that cam, according to the positions at the time occupied by the guidhway H.

An adjustable brake P is preferably provided to prevent oneigrunning ot the mutil'atetlgear Wheel 107 when it runs out" of mesh with the gear \vl1'eel105 in the arrangomel illustrated, this bralceis inthe form of a band partially encircling the disc 109, and capable of'being slackened or tightened by a Wingednut 4 Frointhie foregoing it will be seen th'at when an operative cli'angeot n'Iagazineis to be brought about by adustment ot the guidewayll, all that the operator ishcalled upoii to do isto depress the light-touch key A which results in the projectionof the re spective plunger- 118 into the path of the arm 19?, which, tl'n'ougli that, plunger; turns the mutilated gear u heellOT into mesh with the constantlyrotated gear Wheel 105. The

earn 108 is thus turned through 180 and raises or lowers the front end oi? the levertr,

which, through the before-described connections, correspondingly raises or lowers the guideway H puringthis semi-rotzttion the cam 123 pushes the respectlve plunger 118 out of the path of the arms 122 so thatwhen that portion of theirotation is conijpleted' and the respective mutilation of the Wheel 107 is presented to the gear Wheel 105, the said wheel 107 and cam 108 are stopped by the action of the brake PL i The arrangement as described above and illustrated in the drawings is designed. to eflect changes from one to another of tWo ma azines' but it will be reco nized that nisiin having zines may be provided for.

Having described my invention, I declare that What I claim and desire to secure by Letters Patent is 1. In a typographical composing machine,

h a thecombmation ot a plurality of superposed inclmed magazines, and assembling 1nechanatively' into voperative register withrelatively different magazines, with a mechanical a guideivay adjustable altei' y, I vsignature hereto.

relay comprising a mutilated gear rotatable on a fixed axis and a constantly rotating gear wheel with Which the mutilated gear is capable of meshingrifor a partialrotation only ateach cycle of operation, means operatively connecting the relay with the ad just able guideway andoperatiye at each cycle of operation of the relay to move the guideway into one or another ofits different operative positions, said means including a 'natively into operative register With relatively diil'erent magazines, Wililll mechanical relay comprising a mutilated gear rotatable on a fixed axis and a constantly rotating gear Wheel with which the mutilated gear is capable of meshing for a partial rotation only at each cycle ofoperation, a cam operatively fast to the mutilated gear-Wheel, a lever engaged by the cam and operatively connected to the" adj ustable guideway With the capacity for moving it into andout of operative register with one or another of the respective magazines at each cycle of operation of the cam, said connection including a verticallyreciprocatory spring-actuated rod operated by said lever, and a lever and link connection between said rod and the guiden' ay, together With a lightstouch finger key mechanism controllingthe operation of the relay. 1 i

3. In a typographical the combination with mechanismaccording to claim 1, ot a friction brake adapted to prevent over running of the anutilated gear WlIEGl when a mutilation thereof is presented to the constantly rotatingge'ar Wheel. i 1
